Description
TECHNICAL FIELD

[0001] The invention in one embodiment relates generally force transmission and more particularly to transmission of force through contacting of face portions of components.

BACKGROUND

[0002] One example of a device that employs force transmission is a tool such as wrench. One example of a wrench comprises a ratchet wrench. One implementation of a ratchet wrench employs a pawl that serves to transfer force to teeth on a gear wheel of the ratchet wrench by engaging only a relatively small part of the wheel at any one time for transmission of force. As one shortcoming, such an implementation employs an undesirable concentration of force between the pawl and the engaged teeth.

[0003] Another implementation of a wrench employs roller bearings. In one design of such a wrench, the roller bearings present a shortcoming of having a tendency to undesirably slip upon application of relatively high torque.

[0004] Thus, a need exists for enhanced employment of face portions of components for force transmission. A further need exists for enhanced distribution of force that is transmitted through face portions of components.

SUMMARY

[0005] Pursuant to one embodiment of the invention, shortcomings of the existing art are overcome and additional advantages are provided through the provision of force distribution components and spreader components with contactable substantially flat face portions for force transmission.

[0006] The invention in one embodiment encompasses a device. The device includes a plurality of force distribution components and a plurality of spreader components. The plurality of force distribution components, upon operative location of the plurality of force distribution components relative to one or more force coupler components, are movable among a plurality of first positions relative to the one or more force coupler components. The plurality of force distribution components comprise a force distribution component that comprises one or more substantially flat first face portions. The plurality of spreader components are movable among a plurality of second positions relative to the plurality of force distribution components. The plurality of spreader components comprise a spreader component that comprises one or more substantially flat second face portions. Location of the plurality of spreader components at one or more force transmission position sets of the plurality of second positions causes, through employment of contact of one or more of the one or more substantially flat first face portions with one or more of the one or more substantially flat second face portions, location of the plurality of force distribution components at one or more force transmission position sets of the plurality of first positions.

[0007] Another embodiment of the invention encompasses a device. The device includes a plurality of force distribution components, a plurality of spreader components, and one or more second force coupler components. The plurality of force distribution components, upon operative location of the plurality of force distribution components relative to one or more first force coupler components, are movable among a plurality of first positions relative to the one or more first force coupler components. The plurality of force distribution components comprise a force distribution component that comprises one or more substantially flat first face portions. The plurality of spreader components are movable among a plurality of second positions relative to the plurality of force distribution components. The plurality of spreader components comprise a spreader component that comprises one or more substantially flat second face portions and one or more substantially curved face portions. The one or more second force coupler components are movable among a plurality of third positions relative to the plurality of spreader components. The plurality of force distribution components, the plurality of spreader components, and the one or more second force coupler components serve to allow one or more finite angular movements between the one or more first force coupler components and the plurality of force distribution components. One or more of the one or more finite angular movements is less than or equal to five degrees.

[0008] A further embodiment of the invention encompasses a method. There are selected a plurality of force distribution components that, upon operative location of the plurality of force distribution components relative to one or more force coupler components, are movable among a plurality of first positions relative to the one or more force coupler components. The plurality of force distribution components comprise a force distribution component that comprises one or more substantially flat first face portions. There are selected a plurality of spreader components that are movable among a plurality of second positions relative to the plurality of force distribution components. The plurality of spreader components comprise a spreader component that comprises one or more substantially flat second face portions. Location of the plurality of spreader components at one or more force transmission position sets of the plurality of second positions causes, through employment of contact of one or more of the one or more substantially flat first face portions with one or more of the one or more substantially flat second face portions, location of the plurality of force distribution components at one or more force transmission position sets of the plurality of first positions.
